Use this page to explore 2007-2020 EHDI data. Variables are ordered with reported variables first, followed by calculated variables, and presented alphabetically within each group. Figures are interactive allowing you to hover for more information, zoom in/out, or download a plot as PNG (among the tools in upper right of each plot).

“US” data is gathered from/calculated from the CDC totals reported in each year, which includes states and territories. “State average” and “State median” were calculated from available state data in a year, including the 50 states and District of Columbia.


Hearing loss prevalence

This section takes a look at HLp, Prevalence of total hearing loss. It was calculated using the formula HL / Tscr * 1000. Decision makers can easily identify the regions with higher prevalence need additional investment in audiology services and regional disparity..

States above and below 2020 median HLp value by year, 2014-2020

Figure displays the numbers of states above and below the 2020 median HLp value. Mouse over the bars to see the percentage of states reporting above or below the 2020 median each year.

States above and below 2020 median HLp value by year, 2007-2020



Smoothed line plots

Figure 2 shows the HLp value by state (pink lines) and smoothed trend lines (green) to discard small year-to-year variations. States are ordered from top to bottom by their latest HLp values. The black dots represent the state median in 2020 for comparison. Remove either type of line from all states in the figure by clicking on the legend (bottom right).

Comparison line plots

Figure shows the HLp by state and for the US overall along with annual state mean and median. Hover over a point to get state, year, HLp value, and quartile (Highest, Moderately High, Moderately Low, Lowest). Click on a line or point to isolate it, or choose one or more lines to compare from the dropdown menu. Double-click in the whitespace to bring all the lines back. To zoom in after selecting states for comparison, drag and drop the mouse from left to right over the plot area. If applicable, the range of the axes will change to fit the selection.

Notes:

  • It may take a little practice on a touch device to master all the features.

  • Line color in Figure 3 is only to make visualization easier.

  • Hold down “Shift” to select multiple lines.

Boxplots

Figure shows the distributions of states’ HLp values in boxplots by year. The area in the box begins with the first quartile (25th percentile). The middle line represents the median data point, and the top of the box is the third quartile (75th percentile). The whiskers (lines beyond the box) show the minimum value on the bottom,or the lower fence when outliers are present. The upper fence is at the top of the line. The fence values represent where the minimum and maximum values would be if the distribution were normal. Dots above and below the whiskers represent outliers. Mouse over the boxes and whiskers to view all these statistics.

The overall trend for the median and maximum values for states’ HLp is increasing most years, though small decreases in some years. This year-to-year oscillation is likely statistical noise.

Heatmap

In the figure, states are ranked and color coded in 4 fixed HLp ranges. These ranges are determined by 2020 quartiles. In this way, it is possible to see how the distribution of states (in the fixed intervals defined in the key) has changed over time. States are ordered from highest (top) to lowest (bottom) average HLp (top to bottom). Mouse over any box for more information. Click on a state or states to isolate all years for the selection.

Note:

  • The figure shows how states having HLp > 1.81 steadily increase in number 2007-2017, while showing a curious reversal of this trend 2018-9.

Annual state map: HLp, 2007-2020

Data not available for every state in 2014-2020. See Data Availability Table for years of missing data for each state/variable. If a map does not populate, it is because data was not available for all states in that year. For example, there were no data available for total passed outpatient screening in 2014.
